IMPROVEMENT IN MACHINERY FOR MAKING CORDAGE.`

Specification forming part of Letters Patent No. 10,559, dated February 21,718.54.

.To all whom it may concern:

Be it known that l, RUFUs PORTER, of the city and county of Washington, in the District of Columbia, have invented a new and useful Improvement in Cordage-Machines; and I do.

hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a front elevation, a part of the front post being removed for the purpose of showing the worm. Fig. 2 is alvertical transverse section on the line O O of Fig. 1. Fig. 3 is a vertical View of the conducting-plate and conducting-pulleys. Fig. 4 is a transverse section of one of the iiiers, showing especially the friction-spring which presses upon the bobbins. Fig. 5 is a transverse section of one of the iliers, showing especially one of the insulating-plates; and Fig. 6 is a transverse section of the twist-shaft on the line X X of Fig. 1 and representing 'the geared trigonal rolls.

Upon a horizontal platform A are erected live posts B C D E, two of which (B and D) support the bearings of a horizontal shaft F, the right end of which is furnished with a crank G (or with a gear or band wheel)to Upon this shaft, between the posts C and D, is mounted a band-Wheel, which is connected by a belt Il to a pulley y upon the right end of a twistshaft K, directly over the shaft F, and upon which are mounted two wheels L and N. The shaft K has its right bearing in the post D and its left in a transverse beam a, which is supported by two parallel side posts (front and rear) E, which also support the bearings of a drum M. Three parallel fliers PYP, arranged at equal distances from each other, have their bearings in the two wheels L N, near the peripheries thereof. Each iiier consists of two flier-heads b and d, connected by two parallel flier-bars -m m, which are also connected by a cross-bar c, to the right side of which is attached a friction-spring e, as represented in Fig. 4t, in the center of which is an aperture to receive the left end of a center rod, (not represented,) the right end of which is inserted in the center of the right flierhead d. Upon each center rod are mounted three Vor more bobbins or spoolsv S, each of left bobbin, and between each two 'bobbins is an insulatingplate n, (see Fig. 5,) to prevent any influence which the motion of one bobbin might. otherwise have upon that of another, the plates being restrained by the flier-bars from revolving upon the center rod, While the pressure of the spring e upon the left bobbin produces a uniform frictional resistance to the motion of each upon its axle. To the centerward side of one of the bars of each iiier, and opposite each bobbin is attached a small hook r, and a thread of yarn from each bobbin passes up over its respective hook, and thence to the left through the cross-bar c and through an orifice in the center of the left flier-head.

Fromthe left side of the wheel L, at equal distances from each other and at points intermediate between the bearings of the fliers, project three parallel arms R, which constitute or support the bearings of six equalizing-rolls f g, three of which g have gear-teeth at the ends thereof, whereby the three connect with each other, as represented in Fig. 6. The peripheries ofeach parallel pairI of rolls are in contact, or nearly so, and each has a groove round its longitudinal center.

The several threads from each tliergconst'itute one strand o of the cord, and each strand passes to the left over and around the roll f,

back over the roll g, and thence 'to an aperture in the side of the twist-shaft K near the beam a, and the three strands, being united at thev center of the shaft K, pass to the left through an orifice in the center thereof to the periphery of the drum M.

The three iiier-heads d are embraced by a belt l, to which is attached an elastic checkstrap J, the opposite endof which is attached Y to the front of the platform. Thisbelt and velastic check have the `effect to cause the fliers to revolve upon their respective axles in the direction contrary to that of their rotation round the shaft K, and by this planet movement each strand is twisted in one .di-

rectiol, while the three are laid and twisted together in a contrary direction by the rotation ol the shaft K.

The wheel L is connected by a band 7L to the left end of a conical pulley U, which is also connected by another band i to -"a reversed conical pulley V, the left end of which terminates in a Worm w, which takes to a inothed hoop Y, which Compasses the center ot' the druni M. The left end of the Worm w has its bearing in a cross-bar q, the front end ot' which enters a slot or mortise in the front post. E and rests upon a key or Wedge S, which being occasionally withdrawn the bar q is depressed so as to disconnect the Worm fw from lhe drum M. Each conical pulley has several grooves n to receive occasionally the band if, whereby the motion of the drum is regulated to produce the required compactness in the twist of the cord.

Between the posts F and to the left of the beam ct is a horizontal plate Z; (represented in Fig'. 3,) upon which, near the left bearing ofthe twistshaft, are mounted two conductd ingpulleys x 5c, which revolve upon two Vertical aXle-pins, and near the left edge of the plate Z is a ro .v of holes o v, into one of which is inserted another axle-pin, upon which revolves another conducting-pulley e. This pin may be placed in any of the holes for the purpose of conducting the cord to any part 0f the drum, as occasion may require.

Vha-t I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement substantially as herein described, and the combination oi the fliers, rollers, and drum by which the longitudinal motions of the strands between the fliers and the laying-point are equalized, the said rollers being made to rotate on their respective axles by the tension of the rope and strands.
